Recording for the poor

I want to record, on my computer if possible, but I'm broke. I have $400 but i NEED it for my amp. I downloaded Quartz, but my soundcard sucks so bad that the tracks were out of sync when I recorded. Any suggestions, or am I hopelessly screwed?

i don't even know what kind of soundcard i have (not too big with the hardware junk). My computer is a rebuilt piece of crap. I think I'll wait till i get a new computer... but my parents aren't giving in, it seems.
